Does the VRAM usage change if you use different backgrounds types? I've tried "Image" and "Slideshow" and they both use over 900MB of VRAM. Thanks. Does it create an observable problem at all? I mean, it uses a lot of VRAM. My use-case is that sometimes I use my desktop (which has the best GPU) to run local LLMs while it's idle, if kscreenlocker uses 1GB of that, that's a lot less context tokens I can use for the LLM. After messing around with it a bunch more, I find that commenting out the WallpaperFader part of /usr/share/plasma/shells/org.kde.plasma.desktop/contents/lockscreen/LockScreenUi.qml (not sure if it's a different path depending on distro) reduces the VRAM usage by half, down to about 500MB rather than almost a gig. For what it's worth, when my laptop is in locked mode the fans speed up a lot. I have tried checking into what process is causing this but I am not sure. When I exit the lock screen the fans go back to normal and cpu and ram usage falls. |
